Concluding Remarks,Science and technology of silver halide photography have again made remarkable progress in performance during the last 35 years, particularly in reaching higher sensitivity and higher image quality. This imaging medium is dominating as always; thus nowadays about 66 billions of color prints are produced worldwide every year.

Heterocyclic Stabilizers and Antifogging Agents,oup of stabilizers and antifoggants. Thus, invariably every second stabilizer patent has claimed heterocyclic substances (Table 2.2). Among them, the well- known structures of 4-oxo-6-methyl-l,3,3a,7-tetraazaindene (., .), benzotriazole (., .), and l-phenyl-5-mercaptotetrazole (., .) are typical exa
